REFERENCE

The present application is a continuation application of U.S. patent application Ser. No. 15/241,671, filed Aug. 19, 2016, the entire content of which is incorporated herein by reference.

FIELD

Various embodiments of the disclosure relate to data communication and media processing. More specifically, various embodiments of the disclosure relate to a system and method for customized message playback.

BACKGROUND

Various electronic devices, such as security or surveillance systems, may be used in premises, such as a household, an office, or an industrial establishment, to secure entrances, occupants, and/or other valuable goods in the premises. The electronic devices may also serve to interface between visitors and occupants of the premises. For instance, when a visitor arrives at household premises, the visitor may press a doorbell button at an entrance of the premises, which may output a bell or tune from the doorbell to an occupant of the household premises. When the bell or tune is played, the occupant may become aware of the arrival of a visitor at the household premises. In certain scenarios, the doorbell may be integrated with the security or surveillance system of the premises. For example, a camera (such as a CCTV camera) associated with a surveillance system may capture images of the visitor. The captured images of the visitor may be displayed to the occupant of the premises via an electronic device situated inside the premises or associated with the occupant. However, such existing systems may not provide a user-centric experience customized to both the visitor and the occupant(s) of the premises. An advanced eco-system may be required to not only enhance security of the premises, but also provide a platform that may augment usability of a smart security system while providing an enhanced experience to the end-users.

Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of described systems with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings.

Another tune, such as “Peter is standing outside, open the door”, may be played back to the occupant, such as the second user 108 a.

The registration may enable the second electronic device 106 a to interface with the first electronic device 102 installed at the premises 120. The registration of the second electronic device 106 a may enable the second electronic device 106 a to receive custom messages and/or alerts from the first electronic device 102. Further, the registration may enable the second electronic device 106 a to transmit media items to other electronic devices for storage or play back on that electronic device.

In accordance with an embodiment, when the first user 104 visits the premises 120, the first electronic device 102 may detect arrival of a visitor based on a pre-specified proximity of the first user 104 to the first electronic device 102. In accordance with an embodiment, an input on the first electronic device 102, such as a press a push button (not shown) may indicate an arrival of the first user 104 at the premises 120. The first electronic device 102 may prompt the first user 104 to provide a voice sample through the microphone 214. In addition, the image-capturing unit 212 may capture one or more images of the first user 104.

In accordance with an embodiment, the user recognition circuitry 218 of the first electronic device 102 may be configured to determine one or more physiological and/or behavioural characteristics of the first user 104. The one or more physiological and/or behavioural characteristics may be determined based on facial recognition, voice recognition, and visit trend analysis. The facial recognition, voice recognition, and visit trend analysis steps are illustrated in FIG. 3, as processing steps 302 a, 302 b, and 302 c, respectively.

At processing step 302 a, the user recognition circuitry 218 of the first electronic device 102 may send the captured one or more images, such as facial images, of the first user 104 to the server 110 for analysis. The server 110 may store a repository of facial images of known users. The server 110 may apply one or more pattern detection or face detection techniques and/or one or more image processing techniques to identify one or more facial features of the first user 104. Thereafter, the one or more facial features may be compared with pre-stored facial features in the repository of facial images to determine an identity of the first user 104.

The user recognition circuitry 218 may receive the identified one or more facial features and determined identity of the first user 104 from the server 110. In addition to the one or more facial images, the user recognition circuitry 218 may also transmit one or more full-length images (that capture complete body or a portion of the body) of the first user 104 to the server 110 for analysis. Based on the one or more full-length images, the server 110 may determine one or more other physiological and/or behavioural characteristics, such as a clothing pattern, an emotional state, a current activity of the first user 104, and/or one or more objects held (such as books, knife, or other objects) or worn by the first user 104. The clothing pattern may indicate a profession, such as a doctor, a postman, or age of the first user 104. The server 110 may transmit these determined physiological and/or behavioural characteristics to the first electronic device 102.

At processing step 302 b, the user recognition circuitry 218 may send the captured voice sample of the first user 104 to the server 110 for analysis. The server 110 may include a repository of voice samples of known users. The server 110 may apply one or more sound filters on the voice sample of the first user 104 to obtain an audio signature of the voice sample. Thereafter, the server 110 may compare the obtained audio signature of the voice sample of the first user 104 with pre-stored audio signatures of the voice samples of known users stored in the repository of voice samples. Based on the comparison of audio signatures, the server 110 may determine the identity of the first user 104. The processor 202 of the first electronic device 102 may receive the identity of the first user 104 from the server 110, via the first communication network 116. The identity of the first user 104 may be determined and cross-checked based on a combination of facial recognition (based on the one or more facial images) and voice recognition (based on the voice sample).

At processing step 302 c, the user recognition circuitry 218 of the first electronic device 102 may transmit a request to the server 110, via the one or more transceivers 206, for analysis of a visit trend of the first user 104. The request may include the identity of the first user 104, current date and time, and the determined one or more physiological and/or behavioural characteristics of the first user 104 in the present visit to the premises 120. The server 110 may include a repository of attributes of known users correlated with identity of the known users and visit history log of previous visits of the known users to the premises 120 and/or other premises of other known users.

On receipt of the request from the user recognition circuitry 218, the server 110 may use the identity of the first user 104 to retrieve records associated with the first user 104 from the visit history repository. The retrieved records may include visit history log of the previous visits of the first user 104 to the premises 120 and the correlated one or more attributes of the first user 104. In accordance with an embodiment, the server 110 may analyze the visit history log to determine past trends of the one or more physiological and/or behavioural characteristics of the first user 104. Further, the server 110 may correlate the presently determined one or more physiological and/or behavioural characteristics of the first user 104, received from the first electronic device 102, with past trends determined from the analyzed visit history log.

Based on the correlation, the server 110 may determine one or more current attributes of the first user 104 in accordance with the received one or more physiological and/or behavioural characteristics of the first user 104. The user recognition circuitry 218 and/or the processor 202 of the first electronic device 102 may receive the determined one or more attributes of the first user 104, from the server 110. Further, the server 110 may update visit history repository including the visit history log associated with the first user 104 to include details related to the current visit of the first user 104 to the premises 120. The details related to the current visit of the first user 104 may include the determined one or more current attributes of the first user 104.

At processing step 304, the processor 202 of the first electronic device 102 may retrieve one or more media items from a plurality of media items based on the determined one or more current attributes of the first user 104. In accordance with an embodiment, the server 110 may store a repository of media items including the plurality of media items. The processor 202 of the first electronic device 102 may send a query for retrieval of the one or more media items to server 110. The query may include the determined one or more current attributes. Alternatively, the plurality of media items may be stored in the memory 204 of the first electronic device 102. The processor 202 may retrieve the one or more media items from the memory 204, in such a case. Examples of the one or more attributes may include, but not limited to, an identity of the first user 104, a profession of the first user 104, an event associated with the first user 104, a date-of-interest associated the first user 104. The one or more attributes may further include a type of relationship between the first user 104 and the second user 108 a, a visit history of the first user 104. In addition, the one or more attributes may include a pre-configured schedule of visit of the first user 104 to the premises, and/or a purpose of visit of previous visits of the first user 104 to the premises 120 or other premises.

For example, the one or more attributes may indicate that the identity of the first user 104 is “Peter”. Thus, the one or more retrieved media items may be customized for “Peter”, such as a custom tone and a welcome message for “Peter”, based on the pre-specified preferences. In another example, if the first user 104 may be an individual with a profession of “postman” (determined based on the clothing pattern), the first user 104 may be greeted accordingly. Further, a custom media item may be retrieved and played back in this case, which may instruct the first user 104 to place the new mails and/or periodicals in a mailbox. A password or location of a key of the mail-box may be provided to the first user 104 through the custom message in case the first user 104 may be identified as a trusted/known postman based on the visit trend analysis.

In another example, if an event and/or date-of-interest associated with the first user 104 match with the current date and/or time of identification, a media item may be accordingly selected from the plurality of media items for play back to the first user 104, via the speaker 216. Examples of such events and/or date-of-interest may include, but not limited to, a birthday, an anniversary, and/or an academic or sports performance of the first user 104. For instance, a birthday tune may be selected from the plurality of media items, in case the first user 104 has a birthday on the day of visit to the premises, a previous day (belated birthday), or a next day (upcoming birthday).

In another example, the media items retrieved from the plurality of media items may be based on a type of relationship between the first user 104 and the second user 108 a. For instance, three relationship types, such as family-and-friends, neighbors, and acquaintances/others, may be specified by the second user 108 a via the user interface of the pre-installed application. Accordingly, different media items may be retrieved for the first user 104 who may belong to a particular relationship type. In addition, the retrieval of media items from the plurality of media items may also be based on the visit history of the first user 104, pre-configured visit schedule, and/or purpose of previous visits of the first user 104 to the premises 120. For instance, a technician of a consumer electronic good, such as a television, refrigerator, air conditioner, washing machine, and/or dish washer, may periodically visit the premises 120 to undertake service of the consumer electronic good installed in the premises 120. The periodicity may be quarterly or annual based on service requirement of the consumer electronic good and a service contract of the second user 108 a with the technician's organization. Thus, once the technician is recognized and visit schedule and purpose of visit of the technician correlate with details of previous visits stored in the visit history log, custom media items may be retrieved for the technician. For example, a welcome message followed by details associated with the relevant consumer electronic goods may be provided as an audio/video output to the technician through the first electronic device 102. The details associated with the consumer electronic goods may be retrieved from the server 110, which may store a repository that may maintain such information.

In accordance with an embodiment, once the one or more media items are retrieved at processing step 304, the processor 202 may transmit the one or more media items to pre-registered one or more electronic devices. The second electronic device 106 a may be an example of such electronic device, which may be pre-registered to receive custom messages and/or alerts from the first electronic device 102. The processor 202 may transmit the retrieved one or more media items to the second electronic device 106 a, via the first communication network 116, through the one or more transceivers 206. The one or more media items may be transmitted for playback at the second electronic device 106 a.

At processing step 306 a, the processor 202 may playback a media item from the retrieved one or more media items for the first user 104 on the first electronic device 102. The selection of the media item for the playback to the first user 104 may be based on one or more pre-configured instructions or preferences received from the second electronic device 106 a, during pre-registration of the second electronic device 106 a. Video content of the media item may be played back on the display screen 210, while audio content of the media item may be played back through the speaker 216 of the first electronic device 102.

For the second electronic device 106 a, at processing step 306 b, the second electronic device 106 a may also receive at least one of the retrieved one or more media items for playback to the second user 108 a (the occupant of the premises 120) on the second electronic device 106 a. The play back may be based on one or more pre-configured instructions or preferences of the second user 108 a set during pre-registration of the second electronic device 106 a. The second electronic device 106 a may playback the received media item to the second user 108 a, via a user interface of the application, of the second electronic device 106 a. In accordance with an embodiment, different media items from the retrieved one or more media items may be played back on the first electronic device 102 and the second electronic device 106 a.

In accordance with an embodiment, instead of (or in addition to) transmitting the one or more media items, the processor 202 may transmit an alert message to the second electronic device 106 a, at the processing step 304. The alert message may include a first media item from the retrieved one or more media items. The first media item may be selected from the one or more retrieved media items based on the one or more attributes of the first user 104 and/or one or more pre-specified preferences of the second user 108 a. For instance, a particular media item may be selected and sent as the alert message when the first user 104 is of a specific type, such as, a technician, a neighbor, or a friend, and so on. Hence, when such pre-specified type of the first user 104 visits the premises, the second user 108 a may be sent a particular media item as a special alert on the second electronic device 106 a.

In accordance with an embodiment, the alert message may also include a voice message or an audio/visual (A/V) message recorded by the first user 104 by use of the first electronic device 102. Further, on receipt of the alert message including first media item, the second electronic device 106 a may transmit a second media item to the first electronic device 102, as illustrated in processing step 308 a. The second media item may be pre-specified by the second user 108 a for playback to the first user 104 of a specific type who visits the premises 120. The transmitted second media item may be received by the first electronic device 102 and played back to the first user 104, via the display screen 210 and the speaker 216. In accordance with an embodiment, the second media item may include a pre-configured message that may welcome the first user 104. The second media item may also include a voice message, a text message, and/or an A/V content provided by the second user 108 a by use of the second electronic device 106 a, for playback on the first electronic device 102 for the first user 104.

As shown in FIG. 3, the second electronic device 106 a may present a facial image of the first user 104 via a display screen of the second electronic device 106 a. Further, in case the first user 104 provides a message (such as a voice or an A/V message) through the first electronic device 102, the second electronic device 106 a may receive such message from the first electronic device 102. The received message (such as the voice or A/V message) may be presented to the second user 108 a, via the display screen and/or speakers of the second electronic device 106 a. The second electronic device 106 a may prompt the second user 108 a, via a user interface of the second electronic device 106 a, to grant the first user 104 an access to the premises. Based on an input of the second user 108 a to the prompt, the second electronic device 106 a may transmit an authorization acceptance or a deny instruction to the first electronic device 102 to remotely open a door or reject opening of the door to grant or deny the first user 104 an access to the premises 120. The transmission of the authorization (or access grant) instruction to the first electronic device 102 by the second electronic device 106 a is illustrated in FIG. 3 by processing step 310.

In accordance with an embodiment, on receipt of the authorization acceptance instruction, the first electronic device 102 may automatically unlock the door to grant access to the premises 120 for the first user 104. In accordance with an embodiment, the first electronic device 102 may also be configured to automatically determine whether to grant the first user 104 an access to the premises 120. The automatic determination of whether to grant the access may be based on the determined one or more attributes and/or a temporal analysis of the determined one or more attributes (by analyzing visit history log) by use of machine learning techniques. The first electronic device 102 may automatically unlock the door of the premises 120 based on the automatic determination. For instance, if the first user 104 is a trustworthy person (such as a known technician) who visits the premises 120 quarterly, based on the temporal analysis of the one or more attributes, the first electronic device 102 may grant access to such a user. Alternatively, the first electronic device 102 may send the result of the automatic determination to second electronic device 106 a for confirmation. If the second user 108 a also agrees and grants a permission to the first user 104 to access the premises 120, the second electronic device 106 a may accordingly send an indication to the first electronic device 102. The first electronic device 102 may accordingly control the unlocking of the door of the premises 120 for the first user 104.

FIG. 4 illustrates a second exemplary scenario for implementation of the disclosed system and method for customized message playback, in accordance with an embodiment of the disclosure. With reference to FIG. 4, there is a shown a second exemplary scenario 400, which is described in conjunction with elements from FIGS. 1, 2, and 3.

Further, the second user 108 a may set configuration instructions, via the pre-installed application in the second electronic device 106 a, for selection of appropriate media items in pre-specified conditions and play back of these media items at pre-registered devices (described in detail below). For instance, the second user 108 a may select the third electronic device 106 b and the fourth electronic device 106 c as the other pre-registered electronic devices. For the purpose of the second exemplary scenario 400, the second electronic device 106 a, the third electronic device 106 b, and the fourth electronic device 106 c may be considered as the pre-registered electronic devices.

In accordance with an embodiment, the first user 104 may visit the premises 120 (FIG. 1) of the second user 108 a and use the first electronic device 102 installed in the premises 120 to send a custom message/alert to the second user 108 a. The first electronic device 102 may detect one or more physiological and/or behavioural characteristics of the first user 104. The first user 104 may be identified based on a combination of facial recognition (based on one or more facial images of the first user 104) and voice recognition (based on voice samples of the first user 104). Thereafter, one or more attributes associated with the first user 104 may be determined based on the detected one or more physiological and/or behavioural characteristics of the first user 104.

In accordance with an embodiment, when the first user 104 visits the premises, the first electronic device 102 may transmit a notification to each pre-registered electronic device. The notification may indicate the arrival of a new user (such as the first user 104) at the premises 120 and request for location information related to the pre-registered electronic devices which receives the notification. For instance, in the current scenario, the second electronic device 106 a, the third electronic device 106 b, and the fourth electronic device 106 c are the pre-registered electronic devices. Each of these pre-registered electronic devices, may transmit their respective location information to the first electronic device 102. The transmission of the respective location information by each of the pre-registered electronic devices, is illustrated as processing steps 402 a, 402 b, and 402 c, respectively.

Further, the server 110 may periodically collect location information from each pre-registered electronic device. In accordance with an embodiment, the server 110 may also receive the notification associated with the arrival of the first user 104 at the premises 120. On receipt of the notification, the server 110 may also transmit the last updated location information associated with each pre-registered electronic device. The transmission of the last updated location information of the various pre-registered electronic devices from the server 110 to the first electronic device 102 is illustrated as processing step 402 d in FIG. 4.

As shown in FIG. 4, at processing step 404, the first electronic device 102 may receive the location information from one or more pre-registered electronic devices and/or the server 110. In accordance with an embodiment, the first electronic device 102 may verify the location information received from each of the pre-registered electronic devices with the location information of the corresponding pre-registered electronic device received from the server 110. Further, in a scenario where location information is not received from a pre-registered electronic device, the first electronic device 102 may use the last updated location information of that pre-registered electronic device, as received from the server 110.

At processing step 406, the first electronic device 102 may retrieve one or more media items from the plurality of media items stored in the server 110. Alternatively, if the plurality of media items is stored in the memory 204 of the first electronic device 102, the processor 202 of first electronic device 102 may retrieve the one or more media items from the memory 204. In accordance with an embodiment, the retrieval of the one or more media items may be based on the one or more attributes of the first user 104 and/or the current location information of each of the pre-registered electronic devices. The current location information of a pre-registered electronic device may indicate presence or absence a user associated with the pre-registered electronic device at a preset location of the premises 120.

The first electronic device 102 may transmit the retrieved one or more media items to one or more of the pre-registered electronic devices, based on the received location information of each of the re-registered electronic device. For instance, the one or more retrieved media items (or a pre-selected media item from the retrieved one or more media items) may be sent to a pre-registered electronic device present at the location of the premises 120 of the second user 108 a. The first electronic device 102 may play back one of the retrieved media items for the first user 104. The play back on the first electronic device 102 for the first user 104 may be based on the configuration instructions pre-specified by the second user 108 a. That is, a custom message including the media item selected from the one or more retrieved media items for the first user 104 may be played back on the first electronic device 102, as illustrated in processing step 408 a.

As shown in FIG. 4, a selected media item from the retrieved one or more media items may be played back on each of the pre-registered electronic devices. The playback of the selected media item on the pre-registered electronic devices, such as the second electronic device 106 a, the third electronic device 106 b, and the fourth electronic device 106 c, is illustrated in processing steps 408 b, 408 c, and 408 d, respectively. The selection of the pre-selected media item from the retrieved one or more media items and the playback of the selected media item may be based on the location information of the respective pre-registered electronic device.

For instance, the second user 108 a and the fourth user 108 c may be present at the premises 120. In this case, at processing step 406, the first electronic device 102 may send a first media item to the second electronic device 106 a and a second media item to the fourth electronic device 106 c. In accordance with an embodiment, the first pre-selected media item sent to the second electronic device 106 a may be different from the second media item sent to the fourth electronic device 106 c, based on pre-specified configuration instructions. For example, the first media item sent to the second electronic device 106 a may include a tune preferred by the second user 108 a. The second media item may include a tune preferred by the fourth user 108 c that may be sent to the fourth electronic device 106 c. The second electronic device 106 a and the fourth electronic device 106 c, may playback the received first media item and the second media item, for the second user 108 a and the fourth user 108 c, respectively, as illustrated in processing steps 408 b and 408 d.

In accordance with an embodiment, based on the location information of the second electronic device 106 a, the first electronic device 102 may initially send one of the one or more retrieved media item to the second electronic device 106 a. The media item may be a customized media item for the second user 108 a, such as with a custom tune (“Hi John <the second user 108 a>, Peter <the first user 104> is standing outside the door of your home <the premises 120>”). If no response is received from the second electronic device 106 a by the first electronic device 102 within a pre-specified time interval, the first electronic device 102 may select and send another media item to the fourth electronic device 106 c. The fourth electronic device 106 c may be chosen for the transmission of the other pre-specified media item based on the location information of the fourth electronic device 106 c that may indicate its presence at the location of the premises 120. The other pre-specified media item sent to the fourth electronic device 106 c may be customized for the fourth user 108 c (another occupant), such as “John <the second user 108 a> is not responding; Peter <the first user 104> is standing outside the door of your home <the premises 120>”). The communicated media item, in both the cases, may include a message that may indicate that the first user 104 has arrived at the premises 120. In accordance with an embodiment, a specific media item or tune may be played for a specific user based on the user identification.

In accordance with an embodiment, the pre-registered electronic devices that may be present at the location of the premises 120 may perform the associated processing steps of media item playback (that is, processing steps 408 b, 408 c, and 408 d). For instance, as per the aforementioned example, the second electronic device 106 a and the fourth electronic device 106 c, may be present at the premises 120. Hence, respective media items from the one or more retrieved media items may be received by the second electronic device 106 a and the fourth electronic device 106 c. Further, the second electronic device 106 a and the fourth electronic device 106 c may play back the received media items, as shown in the processing steps 408 b and 408 d, respectively. However, if the third electronic device 106 b is not present at the location of the premises 120, the third electronic device 106 b may not receive a media item. Hence, the third electronic device 106 b may not perform the corresponding media play back step, illustrated by the processing step 408 c.

FIG. 5 illustrates a third exemplary scenario for implementation of the disclosed system and method for customized message playback, in accordance with an embodiment of the disclosure. With reference to FIG. 5, there is a shown a third exemplary scenario 500, which is described in conjunction with elements from FIGS. 1, 2, and 3.

The second communication network 118 may connect the first electronic device 102 and the plurality of network devices 112. As shown in FIG. 5, the first electronic device 102 may perform processing steps 504, 506, 508 and 510 a to 510 c. Further, the second electronic device 106 a may perform processing steps 502 and 510 b. The first set of network devices 514 may perform processing steps 510 c, while the second network device 112 b and the third network device 112 c are shown to perform processing steps 512 a and 512 b, respectively. The third exemplary scenario 500 also depicts a first set of network devices 514 that may include one or more network devices from the plurality of network devices 112. For instance, the first set of network devices 514 is shown to include the second network device 112 b and the third network device 112 c.

In accordance with an embodiment, the second user 108 a may provide input on the second electronic device 106 a, via the user interface of the pre-installed application, for registration of each network device of the plurality of network devices 112. Further, the second user 108 a may specify one or more rules for grouping of the network devices into various logical groups. For example, one or more network devices may be grouped into a first group associated with friends and family members of the second user 108 a. One or more other network devices may be grouped into a second group associated with neighbors of the second user 108 a.

In addition, the second user 108 a may specify rules related to selection or play back of media items for network devices that belong to different groups. For instance, messages/alerts related to a visit by a user (such as the first user 104) to the premises 120 of the second user 108 a may also be sent to each network device that belongs to a friends and family group, such as the first set of network devices 514. This may be the case when the second user 108 a is out of station. Further, the messages/alerts related to a visit of the first user 104 of a specific type (such as a postman) may be sent to each network device that belongs to group of network devices belonging to neighbors of the second user 108 a. For instance, through the playback of custom messages/alerts, the neighbors may be requested to keep the mail and/or periodicals related to the occupants of the premises 120 of the second user 108 a.

In accordance with an embodiment, the first user 104 may visit the premises 120 of the second user 108 a and use the first electronic device 102 installed in the premises to send a custom message/alert to the second user 108 a. The first electronic device 102 may determine one or more physiological and/or behavioural characteristics of the first user 104. The first user 104 may be identified based on a combination of facial recognition (based on one or more facial images of the first user 104) and/or voice recognition (based on voice sample of the first user 104). The first electronic device 102 may then determine one or more attributes of the first user 104 based on the determined one or more physiological and/or behavioural characteristics, as explained in FIGS. 1 and 3.

In accordance with an embodiment, when the first user 104 visits the premises of the second user 108 a, first electronic device 102 may transmit a notification to the second electronic device 106 a indicating arrival of a new user. The notification may further request the second electronic device 106 a to transmit current location information associated with the second electronic device 106 a to the first electronic device 102. As shown in FIG. 5, at processing step 502, the second electronic device 106 a may transmit the current location information associated with the second electronic device 106 a to the first electronic device 102.

At processing step 504, the first electronic device 102 may receive the current location information associated with the second electronic device 106 a from the second electronic device 106 a. At processing step 506, the first electronic device 102 may select the first set of network devices 514 from the plurality of network devices 112 for transmission of custom messages/alerts. The selection of the first set of network devices 514 from the plurality of network devices 112 may be based on the current location information and/or pre-specified configuration instructions received from the second electronic device 106 a. For instance, the location information of the second electronic device 106 a may indicate that the second user 108 a is out of station. Further, the pre-specified configuration instructions may indicate that network devices of family and friends are to be grouped together and notified about visitors to the premises 120 during the time the second user 108 a is out of station. Thus, in this case, the first set of network devices 514 selected from the plurality of network devices 112 may correspond to the group of network devices associated with friends and family members of the second user 108 a.

As shown in FIG. 5, at processing step 508, the first electronic device 102 may retrieve one or more media items from the plurality of media items stored at the server 110. Alternatively, the processor 202 of the first electronic device 102 may retrieve the one or more media items from the memory 204, in case the memory 204 stores the plurality of media items. The retrieval of the one or more media items may be based on the received location information and/or the one or more attributes of the first user 104. In accordance with an embodiment, the first electronic device 102 may retrieve media items for play back at different electronic devices and/or network devices.

For example, the first electronic device 102 may play back one of the retrieved media items for the first user 104, based on the one or more attributes and the current location of the second user 108 a. The selection of media item from the one or more media items for play back on the first electronic device 102 for the first user 104 may be based on pre-specified configuration instructions by the second user 108 a. That is, a custom message including the media item selected from the one or more retrieved media items for the first user 104 may be played back on the first electronic device 102, as illustrated in processing step 510 a. Further, if the second user 108 a is determined as out of station based on the location information, an appropriate media item may be retrieved from the plurality of media items based on the one or more attributes. If the one or more attributes indicate that the first user 104 is a known/trustworthy individual, the retrieved media item may indicate to the first user 104 that the second user 108 a is out of station.

In addition to the media items retrieved for the first user 104, the first electronic device 102 may also retrieve media items for the second user 108 a based on the location information of the second electronic device 106 a. If the second user 108 a is determined to be present at the premises 120 associated with the second user 108 a, a selected media item may be sent to the second electronic device 106 a. The reception and play back of the selected media item by the second electronic device 106 a, is illustrated by processing step 510 b. Alternatively, if the location information indicates that the second user 108 a is present at premises of a known user, such as the first remote user 114 a, a custom message associated with the known user may be retrieved based on the one or more attributes. That is, the retrieved media item may include a custom greeting for the known user and the second user 108 a and also indicate the type of the first user 104 and other attributes of the first user 104. This retrieved media item may be sent to the network device (such as the first network device 112 a) of the known user (such as the first remote user 114 a). The reception and playback of the pre-specified media item by the first network device 112 a is illustrated by processing step 510 c.

The playback of the pre-specified media item on the first network device 112 a may be controlled based on pre-specified configuration instructions received along with the communicated media item, from the first electronic device 102. In accordance with an embodiment, the pre-specified configuration instructions may be received from the second electronic device 106 a (of second user 108 a) during pre-registration of the first network device 112 a and/or the second electronic device 106 a. For instance, the pre-specified configuration instructions may direct the first network device 112 a to playback a portion of the received media item and then playback an alert tone. Further, the first network device 112 a may be directed to send the received media item to an electronic device, such as a smartphone, of the first remote user 114 a if no response is received from the first remote user 114 a within a predefined time interval.

In accordance with an embodiment, another media item may be retrieved for play back on the first set of network devices 514. The other media item may indicate the one or more attributes (such as type of the first user 104, purpose of visit, etc.) and also include a custom message for users of the first set of network devices 514. For instance, the custom message may include a preferred tune or greeting for each user of the first set of network devices 514. The selection of first set of network devices 514 from the plurality of network devices 112 based on the location information of the second user 108 a is explained above in processing step 506. In accordance with an embodiment, the other media item may be selected from the one or more retrieved media items based on the current location information of the second user 108 a and the determined one or more attributes of the first user 104. For instance, the first set of network devices 514 include network devices of friends and family who may receive custom messages and alerts when the second user 108 a is out of station. Hence, when the location information of the second user 108 a indicates that the second user 108 a is out of town, the first electronic device 102 may send custom messages/alerts to the first set of network devices 514. The first set of network devices 514 may playback the received message and/or pre-specified media item for the second remote user 114 b and the third remote user 114 c, as illustrated by processing step 510 c.

In addition, the first electronic device 102 may post a customized message on a social media profile of the second user 108 a when the first user 104 visits the premises of the second user 108 a. Further, certain play back rules may be applied to network devices of various groups of users based on characteristics or preferences of the users and/or their relationship with the second user 108 a. For instance, as an aged individual may be hard of hearing, network devices belonging to the aged individuals may play back media items at a high pitch and volume.

In accordance with an embodiment, during the pre-registration, the second user 108 a may provide input related to events and date-of-interest of other users including users of the plurality of network devices 112. Examples of such users may include the first remote user 114 a, the second remote user 114 b, and the third remote user 114 c. Examples of the events may include, but not limited to, a birthday, an anniversary, an academic performance, a sports performance, or a date associated with a personal or professional accomplishment. In accordance with an embodiment, the second user 108 a may provide custom greeting and tunes associated with different event types. Further, the second user 108 a may provide pre-specified configuration instructions based on preferences of the concerned users for appropriate selection of the custom greetings and tunes. Thus, the greetings and the tunes may be customized by the second user 108 a, by use of the second electronic device 106 a, based on the event and preferences of the concerned users.

In accordance with an embodiment, certain media items may also be automatically retrieved and played back at a pre-scheduled date and time at a specific network device of the plurality of network devices 112. Based on the date-of-interest of a user, the first electronic device 102 may retrieve a custom message including a pre-selected media item (such as a customized birthday greeting tune) for the user. The first electronic device 102 may then select a network device associated with the concerned user and transmit the custom message including the pre-selected media item to that network device on the pre-scheduled data and time. For instance, as shown in FIG. 5, at processing step 512 b, the third network device 112 c may receive the custom message including the pre-selected media item from the first electronic device 102. The third network device 112 c may then playback the received custom message, such as “Happy Birthday <Name: the third remote user 114 c>”, to felicitate the third remote user 114 c. In addition to transmitting the custom message to the network device of the concerned user (such as the third remote user 114 c), the first electronic device 102 may also transmit a reminder message to the second electronic device 106 a. The reminder message may remind the second user 108 a of the event related to the concerned user (that is, the third remote user 114 c, in this case).

A person with ordinary skill in the art will understand that the exemplary scenarios 300, 400, and 500, are provided for illustrative purposes and should not be construed to limit the scope of the disclosure. The disclosure may be implemented in various other scenarios with one or more variations, without departure from the scope of the disclosure.

In accordance with an embodiment, the premises 120 may not be restricted to an official building or a residential complex associated with the second user 108 a. In accordance with an embodiment, the disclosure may be implemented for other premises, such as an airport, a railway station, bus-stands, ship ports, and other transportation terminals. For instance, the first user 104 may correspond to a traveler and the first electronic device 102 may correspond to an electronic device installed at a ticketing counter or check-in counter of the terminal. The first electronic device 102 may automatically verify the identity of the travelers (such as the first user 104) based on a combination of facial recognition and voice recognition for auto-check in. Further, custom messages or alerts may be delivered to electronic devices of relevant authorities in case of fraud or suspicion based on detection of one or more physiological and/or behavioural characterizes of the traveler. In addition, the first electronic device 102 may be used in various other implementation scenarios. For instance, the first electronic device 102 may be used as an automated office assistant or receptionist at an office premises that may be configured to playback custom messages to interface office bearers and visitors, such as during a client visit.

At step 606, one or more physiological and/or behavioural characteristics of the first user 104 may be detected. The detection of the one or more attributes of the first user 104 has been explained in FIG. 1 and FIG. 3. At step 608, one or more attributes associated with the detected one or more physiological and/or behavioural characteristics of the first user 104 may be determined. The processor 202 of the first electronic device 102 may determine the one or more attributes of the first user 104 based on the detected one or more physiological and/or behavioural characteristics, as explained in FIG. 1 and FIG. 3.

At step 610, the first user 104 may be identified. In accordance with an embodiment, the user recognition circuitry 218 may be configured to transmit the one or more images and the voice samples to the server 110. The server 110 may identify the first user 104 by use of facial recognition (based on one or more facial images) and voice recognition (based on voice samples). Thus, the first user 104 may be identified based on a combination of facial recognition and voice recognition. In accordance with an embodiment, the user recognition circuitry 218 may apply one or more machine learning techniques to identify the first user 104, based on a repository of facial images and voice samples of known users.

At step 612, one or more media items may be retrieved from plurality of media items in accordance with the determined one or more attributes of the first user 104. A first pre-specified media item may be selected from the one or more retrieved media items for playback on the first electronic device 102. Further, a second pre-specified media item (different from the first pre-specified media item) may be selected for play back on the second electronic device 106 a. The selection or play back of the first media item and the second media item may be based on pre-specified configuration instructions.

With reference to FIG. 6B, the method of the flow chart 600B may be performed in parallel to methods of the flow chart 600C of FIG. 6C and the flow chart 600D of FIG. 6D. The flow chart 600B progresses to step 614 a from the step 612 of FIG. 6A.

At step 614 a, different media items from the retrieved media items may be played back at the first electronic device 102 and the pre-registered second electronic device 106 a. In accordance with an embodiment, the first media item may be played back at the first electronic device 102.
